One is definitely dead beyond the corrosion issue as it has some light scraping going on. The other is probably repairable as I can get VC continuity on my multimeter by gently wiggling the lead in wires so there is hope for that one.
Financially/logically I reckon I should just sell the Dynaudio woofers but I'm not sure my heart will let me do it - so I'll keep them intact for now and keep my eyes out for some parts. Does anyone know of any 'similiar' replacement drivers? I know Madisound and Falcon Acoustics used to have a non-OEM replacement option but they don't appear to be available anymore either...
I also saw on another post about these that @Zaphod Beeblebrox had modified a set to run a true HF driver rather than the original scan-speaks?

Sorry, what I'm getting at is are they worth enough to put another $400+ in to? I.e. if they're only worth $500 hundred in working order, it wouldn't be a great move to spend $400 fixing em - on my part that is.

G'day guys, I have a giant set of Duntech Viscount PCL-300's in need of some love. It's looking like I'll need to replace the tweeters (aka 5cm scan-speak drivers) as they're toast. I was hoping it was just the corrosion issue I've seen mentioned around but it doesn't appear to be the case.
I bought them out of curiosity but they're too big so I either need to repair and sell or part them out. The woofers, cabinets and grill socks are all excellent and I'm trying to decide if it's worth investing the $440 or so in replacing the Scan-Speaks or if I should just strip them of their Dynaudio woofers and solen MKPs etc and sell for parts.
From what I can tell, they're a fairly rare set of speakers so if anyone has any info, advice or is interested in them I'd appreciate it.

Sorry for the slow reply guys.
Nothing like that. Everything is clean as a whistle.
Thanks Alan,
The deck was running well but went into storage for a while and now it only runs at a super slow speed. Both left and right reels offer very little resistance when the brake is manually disengaged (I'm assuming this is what you meant?), they spin quite freely and smoothly.
The capstan and motor spindles are very clean. The old belt had turned to tar so I had them out and cleaned them thoroughly with isoprop. A new belt was sourced specifically for this model and fits beautifully. I've eye-balled it running and there is no slippage etc from what I can tell.

Hey all, I'm hoping someone on here may have some experience with old TEAC 4-track machines...
I have a a TEAC A-3440 in really lovely condition but at the moment it's running slow and I can't figure out why. The speed of this machine on high should be 15ips but it runs at more like 3 1/2. I've replaced all the belts for the correct replacements, checked that the capstan and motor spin freely. I've cheeked the feed motors and they run freely as well. Everything works perfectly except for the slow speed.
Any ideas would be appreciated

Item: Grace F8 mm cart & stylus
Location: Canberra
Price: $170 inc postage
Item Condition: excellent
Reason for selling: not used / not needed
Payment Method: Paypal, cash on pickup / transfer
Extra Info:
This came on a TT I recently acquired from a deceased estate. Plays beautifully and looks to have had minimal use. The carts aren't terribly rare but an original F8 stylus is hard to come by. Original (I think) screws etc included. will ship in the protective case shown for protection. I did my best to get some photos via a scope, sorry if they're a tad blury.

Hi All, I have a problematic KEF T52b tweeter on my hands at the moment. The tweeter works but I suspect a slightly loose connection somewhere as when it drops out, gently touching the rubber surround brings it back to life for a few more hours.
Has anyone worked on these before? I'm assuming the rubber ring surrounding the dome, if pried up gently, will life the entire diaphragm off?
Poke it around here and it comes good again:
I'd appreciate any advice. Cheers!

Item: RTR 280DRs
Location:
Price: $1200 $1100
Item Condition: 7/10 - awesome for their age
Reason for selling: Dad has upgraded
Payment Method: Pickup - Cash, Paypal, COD Only
Extra Info:
Hi all, I’m selling these beautiful and rare old RTR 280DRs on behalf of my Dad (not to be confused with the cheap RTRs after BIC bought the company in the 80’s). Matching serial numbers 3838 and 3839. The story goes that as an 18 year old, dad had a choice to make – a new car or a stereo system. Needless to say that he choose correctly and they’ve been in the family since new in 1977. It’s actually quite a sad day for both of us really as these were my first introduction to the glorious world of hifi as well – in fact the couple of dinted dust caps were at my own hands as a 5 year old – apologies!
Anyway, here they are in all their Teak clad glory (real Teak, not plastic veneer). They pack in 10 drivers per tower. 5 paper mids/tweeters, a front facing piezo horn, 3 front/side facing 10” woofers and a downward firing 10” woofer. I’ve checked all drivers and they are in good working order.
The rear of the crossovers have pots for treble and mid range as well as an protection override reset button. One speaker will on occasion cut out but a reset is all it needs. The switch probably just needs a clean. The cloth grills look loose in the photos, that’s just due to the screws being removed for me to take photos of the drivers.
The crossovers have recently been recapped with Jantzen MKTs from Speakerbug.com.au. Dad reckons they now sound exactly like he remembered back in 77’ as they had lost a lot of sparkle and bottom end prior to the recap.
Sensitivity wise, I can’t find the original specs but they’re clearly pretty sensitive when compared to my -89dB Martin Logans. Easily over 91-92dB.
They’re not in perfect condition being 41 years old but overall present very well. There has been some loose veneer over the years which has been reglued. One tower has a chip to the bottom rear corner. I’ve tried to show all of this in the photos. A few of the tiny dust caps on the paper tweeters have been pushed in but they’re such shallow caps, I hardly noticed until dad pointed them out.
I’m not sure what else to say about these but please feel free to ask questions. Dad is asking $1200 for them and I realise that’s on the higher end but given their rarity here is Australia it’s probably a fair price
